fyk_L11_4vDopplerFlashAngles

Real-time doppler acquistion and display, each doppler image is computed from ne pages of IQ-frame, and each IQ-frame is compounded by na angles of plane wave.
So far it did not add the Singular-Value-Decomposition(SVD) clutter filtering method, considering the huge computation cost of SVD, it still need a lot of work to realize it in a real-time ultrasonic machine

fyk_L11_4vAcquireDopplerIQ_AnglesSC

Acquire post-compounded IQ data. After one frame in the RcvBuffer is fullfilled, they are reconstructed to pixel-based IQ data and sent to the InterBuffer, and then we use an external function to save this frame of IQ data.

The difference of this script with the previous one is that we add some GUI to this. Specifically, the regin where the doopler sequence will acquire is ploted in the B-mode image, and User can adjust this region when the B-mode is displayed.
A second improvement of this script is that it adopts a method called "Averaging RF", which will transmit two waves in each angle. This method can increase the SNR while it has no need of conducting double DAS opertate.

Adopt the previous script from a linear array to a curved array, so that we can acquire some data of human kidney.
